Why was the data set created?

The Water Resources Development Act (WRDA) of 2000 authorized the Comprehensive Everglades Restoration Plan (CERP) as a framework for modifications and operational changes to the Central and Southern Florida Project needed to restore the south Florida ecosystem. Provisions within WRDA 2000 provide for specific authorization for an adaptive assessment and monitoring program. A Monitoring and Assessment Plan (MAP) has been developed as the primary tool to assess the system-wide performance of the CERP by the REstoration, COordination and VERification (RECOVER) program. The MAP presents the monitoring and supporting enhancement of scientific information and technology needed to measure the responses of the South Florida ecosystem. Hydrologic information throughout the Everglades ecosystem is the key to the development of restoration strategies and for future evaluation of restoration results. There are significant hydrologic information gaps throughout the Everglades wetlands and estuaries that need to be addressed, particularly along Florida’s southwest coast. Among these gaps are flow, water level, and salinity data.

    Date: 2006 (process 1 of 14)
    Several methods were used in the study to describe the magnitude and distribution of flow and salinity at the mangrove transition zone and along the southern coastline of Florida. Field data-collection procedures and discharge calculation techniques for instrumented stations are summarized below. Field data collection water level, temperature, salinity, and discharge data collected at instrumented sites included continuous (15-minute or hourly) measurements of water level, water velocity, salinity/specific conductance, temperature, and periodic measurements of discharge for index velocity calibrations. More information on index velocity techniques is discussed in Hittle and others (2001) and Morlock and others (2002), and Ruhl and other (2005). Stations with transmitting data loggers send field data hourly into the database of the Caribbean Florida Water Science Center (CFWSC) Davie office by way of the Geostationary Operational Environmental Satellite (GOES). Non-transmitting sites are routinely serviced and field data is manually uploaded to the USGS database. Boat mounted acoustic Doppler current profilers (ADCP) were used to measure discharge at the estuarine monitoring stations. The ADCP uses the Doppler shift in returned acoustic signals reflected by particles suspended in the water to determine the velocity of moving water (Simpson 2002 and Oberg and others 2005). The ADCP also has the capability to measure water depth, flow direction, and speed of the boat based on acoustic reflections from the streambed. Discharge and flow direction are both calculated from information provided by the ADCP and computer software. The mean water velocity is calculated by dividing the total measured discharge by the cross-sectional area corresponding to the water level at the time of measurement (Sauer 2002 and Ruhl and others 2005). Acoustic velocity meter (AVM) and acoustic Doppler velocity meter (ADVM) systems were used to measure continuous water velocity. The velocity measured by the ADVM systems represents an "index" of the mean water velocity. The index velocity is a measured velocity at the instrumented sites that can be used to compute the mean channel velocity. Water level data are used to determine water depth and to calculate the stage-dependent cross-sectional area. Water level data were collected by an incremental shaft encoder equipped with a pulley, stainless-steel tape, weight, and float inside an 8 in. polyvinyl chloride pipe stilling well (Sauer 2002), pressure sensors, or acoustic transducers. Corrections to water level data follow USGS quality assurance quality control protocols (Rantz and others 1982 and Sauer 2002). Salinity is measured near the water surface and the bottom of the water column to help determine the presence of freshwater flow and to examine potential effects on the acoustic signals caused by salinity stratification. Continuous salinity measurements are important for describing the seasonal patterns of freshwater flow (wet/dry season) and for identifying bi-directional flow. Elevations of the continuous monitors are available upon request. Temperature is measured to acquire physical information on creek or wetland characteristics, and to monitor possible vertical gradients that also could affect acoustic signals. Due to biological fouling and electronic drift, the continuous monitor requires routine cleaning and calibration to maintain data quality. During the period of record (water years 1996-2003), continuous monitors were calibrated during site visits to ambient conditions using a reference probe (USGS National Field Manual). Ambient salinity conditions were measured with a portable reference probe that was calibrated and or verified against a range of laboratory specific conductance standards. The determination of fouling and drift errors from water year 2003 to current follow the guidelines set forth in Wagner and others (2006). Reference temperature probes are verified against a NIST thermometer prior to field trips. When in situ temperature measurements differ by more than 0.2°C when compared to the reference temperature probe, the in situ probe is replaced. Rainfall monitoring was done with a remote tipping bucket style rain gauge used to measure 15 minute liquid precipitation at Upstream North River, Card Sound Canal and West Highway Creek. Daily rainfall in inches is published by water year. Maintenance consists of routine cleaning of debris from the filter screen, and annual calibration/verification with a known rate and volume dispenser. The gage is adjusted when the calibration error is greater than 5%. Data collection, processing, storage, and publication meet USGS standards (USGS 2006). Format for the hydrology data Water level, discharge, salinity/specific conductance, water temperature, and rainfall data were collected in estuarine creeks, the mangrove/wetland transition zone, and the freshwater wetlands of south Florida. Published data are presented as computed unit-value data under separate files by water year for stations not included in the South Florida Hydrology Data database. The data format used is comma-separated value (csv) files that can be imported into most spreadsheet programs. The data are separated by individual stations (see sites listing), water year (October 1 to September 30), and when necessary, by parameter. Data collection activities varied from real-time instrumented to non-transmitting sites. Salinity/specific conductance and water temperature generally were measured within a few feet of the water surface (near surface) and within a few feet of the river bottom (near bottom). In some cases (wetland or well mixed sites), salinity/specific conductance and water temperature are measured at a single location in vertical profile. Elevations of the continuous monitors are available upon request. Water level is reported in feet as referenced to the North American Vertical Datum of 1988 (NAVD 88), discharge in cubic feet per second, specific conductance in micro-siemens per centimeter, salinity in parts per thousand, and temperature in degrees Celsius. Specific to the Land-Margin Ecosystem hydrologic data only: Data were collected, processed, stored and published with the Land-Margin Ecosystem project followed a study-designed protocol developed from USGS/WRD, state and other federal agencies methods, protocols and standards. These data were neither processed, nor reviewed by the USGS/WRD and should be considered “furnished” data to the South Florida Hydrology Database in accordance to USGS data policy.

    The Shark, Lostmans and Chatham transects were established across the marsh/mangrove ecotone in the southwest coastal Everglades. While these estuaries differ in reach, ecotone and freshwater inflow regimes, they collectively represent the coastal hydrology of the southwestern Everglades. Each gage had a surface and groundwater well to evaluate variability of surface and shallow groundwater hydrodynamics. Data collected and stored at instrumented sites using on site data controller/logger. Stations transmitted data from the loggers every 1 to 4 hours via the Geostationary Operational Environmental Satellite (GOES). Data were transferred from the GOES data retrieval site (Wallops, VA) to Everglades National Park hydrologic database. Non-transmitting sites are routinely serviced and field data is manually uploaded to the database. Surface water level data were collected inside a 12 in. polyvinyl chloride (PVC) pipe stilling well and groundwater level data were collected inside a PVC pipe (4 in.) with a slotted well screen (0.02 ft.) within the limestone aquifer. Surface water salinity was measured near the water surface and groundwater salinity was measured at the well screen. Continuous salinity measurements for both surface and groundwater are important to describe seasonal surface-groundwater hydrodynamic patterns between the wet and dry season. Elevations of the continuous monitors are available upon request. Temperature is measured to acquire physical information variability of surface mangrove and wetlands and shallow aquifer. Due to biological fouling and electronic drift, the continuous monitor requires routine cleaning and calibration to maintain data quality. During the period of record (water years 1996-2003), continuous monitors were calibrated during site visits to ambient conditions using a reference probe. Ambient salinity conditions were measured with a portable reference probe that was calibrated and or verified against a range of laboratory specific conductance standards. The determination of fouling and drift errors followed study guidelines set forth in project SOP document. Reference temperature probes are verified against a NIST thermometer prior to field trips. When in situ temperature measurements consistently differed by more than 1 °C when compared to the reference temperature probe, the field probe was replaced. Rainfall A remote tipping bucket style rain gauge was used to measure hourly minute liquid precipitation at SH1, SH2, SH5, LO1, LO2, LO4, CH1, CH2 and BSC. Daily rainfall in inches is published by water year. Maintenance consists of routine cleaning of debris from the filter screen, and annual calibration/verification with a known rate and volume dispenser. The gage is adjusted when the calibration error is greater than 5%. Data collection, processing, storage, and publication meet study calibration standards. Format for the hydrology data Water level, salinity/specific conductance, water temperature, and rainfall data were collected in freshwater marsh, near the mangrove-marsh ecotone and within the coastal mangrove, Everglades National Park, Florida. Water level is reported in decimal feet as referenced to the North American Vertical Datum of 1988 (NAVD 88), specific conductance in microsiemens per centimeter, salinity in practical salinity units, rainfall in inches and temperature in degrees Celsius.

    accessed as of 7/8/2011 This paper is from the Proceedings of the Joint Federal Interagency Conference June 27 - July 1, 2010 in Las Vegas, NV. The Joint Conference included the 9th Federal Interagency Sedimentation Conference and the 4th Federal Interagency Hydrologic Modeling Conference.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    See: https://water.usgs.gov/admin/memo/policy/wrdpolicy10.02.html https://water.usgs.gov/admin/memo/policy/wrdpolicy10.02_attachment1.pdf

    Data posted here are approved data following the guidelines posted above. Routinely, data from the portal are plotted to identify outliers or suspect data pulls from NWIS. Bryan McCloskey may have other QA/QC filters when storing the data.
  2. How accurate are the geographic locations?
    Horizontal positions were established with the use of GPS equipment.
  3. How accurate are the heights or depths?
    All water level data is referenced to a datum, usually the datum of NAVD 88. Elevations are determined using differential methods or via GPS methods.

    For more information, see: https://sofia.usgs.gov/exchange/gazetteer/methodology.php http://pubs.usgs.gov/tm/tm3A19/ http://pubs.usgs.gov/tm/11d1/
  4. Where are the gaps in the data? What is missing?
    Not all parameters were collected at all sites. Some sites have been discontinued. See the Sites List for Hydrology Data at https://sofia.usgs.gov/exchange/sfl_hydro_data/sitelist.html for a complete breakdown of the data collected for each site.
  5. How consistent are the relationships among the observations, including topology?
    Data collected include stage, salinity, temperature, discharge, specific conductance, rainfall and collection date and time. Not all sites have data for all parameters. Data collected ranged from every 15 minute to 1 hour on specific days during the water year. All water levels are referenced to NAVD-88 datum. Broad River and Lostmans River - NAVD-88 datum corrected, WY2001-2004 records revised as of 12-7-2006. Chatham River and Lopez River - NAVD-88 datum established at these locations, WY2001-2004 records revised as of 12-7-2006. Previous corrections for other sites have been incorporated into the South Florida Hydrology Data database. At the Lostmans River site on September 5, 2009, due to insignificant vertical stratification at this monitoring location the bottom salinity/temp probe was raised to mid-depth and time-series data assumed unchanged. At the Broad River site on March 12, 2008, due to insignificant vertical stratification at this monitoring location the top salinity/temp probe was lowered to mid-depth and time-series data assumed unchanged. At the Chatham River site on March 11, 2008, due to insignificant vertical stratification at this monitoring location the top salinity/temp probe was lowered to mid-depth and time-series data assumed unchanged. Specific to the Land-Margin Ecosystem hydrologic data: Parameters collected include; surface and groundwater levels, surface and groundwater specific conductivities (salinities derived), surface and groundwater temperatures, rainfall and collection date and time. Surface water levels collected hourly from 1995-2003 with 10-tip potentiometer. After 2003, surface water levels were collected every 15 minutes with SDI shaft encoder. Groundwater levels were collected hourly from 1995-2003 with passive resistance tape and every 15 minutes after 2003 with a pressure transducer. Specific conductance data were collected hourly from 1995-2003 with a single torodial sensor and pumping system. After 2003, specific conductance data were collected in situ with a conductance/temperature sonde every 15 minutes.
